I don't really see any reason the scallywag shouldn't be full BAB. It only has one good save, and uses d8s... No class ability is powerful enough warrenting it being brought down, and if you want it to be able to parry often, I would suggest raising its BAB. Any particular reason you didn't make it full?
Anyone else want to chime in?
Possibly the +7 luck bonus to all attack rolls and Reflex saves, and nebulous Luck based effects. That shouldn't be coupled with a good BAB (probably should be reduced with a good Reflex too).
Also everything is arguably luck based so what is intended by luck based should be better defined.
